Abstract
A method for cooling a mold used in the production of plastic parts is described. A capillary feeds liquid carbon dioxide to a channel present in the mold typically used in making plastic parts having thin gaps or thin open sections in the plastic part. The channel will be approximately the same size as the inner diameter of the capillary but will increase in size either stepwise or progressively as it passes through the mold, particularly at the location where cooling is desired therefore providing more effective cooling to the mold and slides and lifters present therein.
